Inhaltsangabe

New materials are required to solve global challenges such as the growing energy demand and reducing the threat of new and re-emerging diseases and infections. Metallopolymers is an exciting and promising area of research and this book focuses on the strategy of incorporating transition metals into macromolecules to design functional materials for addressing such problems.

The book starts with an introduction to current global challenges and the role of materials science in tackling these, it then discusses the fundamentals of metallopolymers and their synthesis. The final chapters look at specific applications of the materials from photovoltaics and light-emitting diodes for energy conservation, to biological sensors and drug delivery platforms.

Written by leading experts in the field, this book is an ideal reference for students and researchers working in polymer chemistry, organometallic chemistry and materials science interested in both the polymers and their applications in energy and health.

CHAPTER 1

Introduction

1.1 Introduction

The contemporary positive transitions in globalization, economic prosperity, and quality of life mark an epoch in human evolution, as do the aftermaths of these changes, which ironically threaten the ecosystem, the planet and human survival. Exponential growth on all fronts of human activities has, indeed, benefited our social, psychological, and biological well-being but has led to enormous pressures on the Earth's resources and the biosphere, pushing the natural system beyond sustainable limits, and challenging our achievements and survival. Climate change, food scarcity, diseases, dependence on unsustainable energy resources, and a widening gap between the rich and the poor are notable examples of these challenges (Figure 1.1). A paradigm shift in our development strategies is crucial to a sustainable future, and indeed, proactive initiatives have been taken by several stakeholders. The United Nations' Sustainable Development Goals agreed upon by the 193 member states in September 2015 exemplify initiatives that seek to address many of the challenges that face contemporary humanity. Materials scientists have also envisaged these problems for decades and have taken concrete steps to help realize a sustainable future. This monograph presents selected contributions from materials scientists, specifically the research and development that uses transition-metal-containing macromolecules to address some of these challenges. Here, the focus is on three challenges: energy, climate change and the burden of diseases, which are central and interconnected to the overall problems facing humanity. For instance, climate change affects food security and biodiversity, energy supply is a major driver of global security, and diseases are a burden to the economy and adversely affect the holistic well-being of the individual.

1.2 Key Global Challenges

1.2.1 Diseases

Science has made unprecedented advancement in disease prevention, diagnosis, and treatment, which has resulted in a significant reduction in mortality and an increase in life expectancy. These achievements notwithstanding, a significant proportion of the world's population are yet to enjoy good health and well-being as exemplified by the 14.1 million new cancer cases diagnosed each year, 387 million people living with diabetes, and 1.1 billion people having high blood pressure. Also, the progress in medicine is challenged by the substantial number of premature deaths, for instance, the over 15.8 million premature deaths from noncommunicable diseases such as cancer in 2015 (Figure 1.2). The majority of these premature deaths are preventable if a healthier lifestyle is adopted or quality health care is provided.

The scenario is bleak in developing countries where 82% of the deaths from noncommunicable diseases occur, and a projected $7 trillion USD will be lost over the next 13 years if the status quo remains. While the situation is better in developed countries whose governments implement policies that reduce risk factors and enable viable health care systems, it is still imperative that the positive epidemiological transition in these countries be sustained and copied in developing countries.

The commendable decrease in the percentage of deaths from communication diseases between 2000 and 2015 (Figure 1.2) is due to advances in medicine, including the development of antimicrobial agents. However, the evolutionary process of natural selection coupled with the selective pressure exerted on pathogens by the overuse and misuse of drugs trigger a new threat: drug-resistant pathogens (Figure 1.2). Undoubtedly, drugs such as antibiotics have greatly benefited humanity, protecting patients from fatal illnesses and mitigating the risk involved in complex medical procedures such as surgery and chemotherapy, but the emergence of resistance threatens the sustainability of these erstwhile effective medical interventions.

Globally, drug-resistant infections including malaria, HIV/AIDS, and tuberculosis kill an estimated 700 000 people yearly, and the number of deaths is projected to increase to 10 million yearly by 2050 if no pre-emptive action is taken. The burden of resistance extends beyond mortality, encompassing the economic, social and security landscapes with an estimated 100 trillion USD of the economy being at risk by 2050 if no action is taken to tackle the problem. The efforts of materials scientists on the research and development of new, affordable and accessible antimicrobial agents/drugs form part of a global action plan to mitigate the burden of antimicrobial resistance.

The therapeutic efficacy and safety of drugs directly depend on the mode of delivery, which includes the dosage form and route of administration. Indeed, drug delivery technologies affect the pharmacokinetics and pharmacodynamics of drugs as well as convenience and compliance of patients. The discovery of a new drug requires the development of a delivery technology that enables the therapeutic function and ensures patients' safety and compliance. Current research on the development of drug delivery technologies seeks to localize therapeutic function at the target cells because this approach maximizes the effect and minimizes the toxicity. The administration of a new generation of highly potent and useful drugs such as peptides, proteins, genes and polymer-based drugs remains challenging due to the inherent problems such as enzymatic degradation, renal clearance, and immune system activation associated with state-of-the-art delivery systems. Indeed, these delivery barriers limit the clinical impact of many drugs and call for next-generation drug delivery technologies that ensure drug stability, specificity, and precise control over drug release, with the ultimate effect of localizing the therapeutic effects and guaranteeing patients' safety and compliance.

1.2.2 Energy and Climate Change

The prosperity and comfort inherent in contemporary lifestyles are strongly dependent on affordable and accessible energy. With a fast-growing population and economic prosperity, especially in developing countries, energy demand is expected to increase. The United States Energy Information Administration expects a 48% increase in 28 years, from the 549 quadrillion British thermal units (Btu) of energy consumed globally in 2012 to 815 quadrillion Btu in 2040 (Figure 1.3). Most likely, an extent of the projected increase could be offset by energy-efficient technologies as governments promote awareness about sustainability but a major energy crisis will persist if we maintain the existing situation. Currently, fossil fuels provide more than 80% of the...
