Photochemistry of small molecules

Photochemistry of Small Molecules

The classic text book in photochemistry is that of Noyes and Leighton, The Photochemistry of Gases published in 1941. In 1966, a comprehensive volume by Calvert and Pitts brought the field up to date, but it soon became obvious that the field of photochemistry was expanding too rapidly to be covered in a single comprehensive volume. In fact, in the latter part of the 20th century organic photoc...

INTERACTION OF PROTEINS WITH SMALL MOLECULES

Photochemistry of organic molecules in microscopic reactors

The photochemistry of dibenzyl ketone and its derivatives has been employed to investigate the ability of zeolite molecular sieves to modify and to control the reaction channels available to organic molecules adsorbed on the internal and external zeolite surfaces. It is found that the observed photochemistry is very sensitive to the size/shape characteristics of the substrate ketones and of the...

Applications of Small Molecules in Muscle Tissue Engineering

Introduction: Skeletal muscles account for about 40% of the total body weight. Every year, hundreds of people lose at least part of their muscle tissue due to illness, war, and accidents. This can lead to disruption of activities such as breathing, movement, and social life. To this end, various therapeutic strategies such as medication therapy, cell therapy and tissue transplantation have been...

Observing and understanding the ultrafast photochemistry in small molecules: applications to sunscreens.

In this review, we discuss the importance of biological and artificial photoprotection against overexposure to harmful ultraviolet radiation. Transient electronic and transient vibrational absorption spectroscopies are highlighted as important tools in understanding the energy transfer in small molecules, with a focus on the application to commercial sunscreens with representative examples give...
