Photo-induced processes in dendrimers

Bioinorganic Photochemistry: Frontiers and Mechanisms

“…An antenna for light harvesting is an organized multicomponent system in which an array of chromophoric molecules absorbs the incident light and channels the excitation energy to the common acceptor component. − The antenna effect can only be obtained in supramolecular arrays suitably organized in space, time, and energy domains. Each molecular component must absorb the incident light, and the excited state obtained this way must transfer electronic energy to the nearby component before undergoing radiative or nonradiative deactivation …”

Design and synthesis of novel fluorescence sensing perylene diimides based on photoinduced electron transfer

“…A characteristic of dendritic macromolecules is the presence of numerous peripheral chain ends that all surround a single core [23,24]. The usage of perylene diimides as dendrimer core would increase their solubility in organic solvents due to the dendritic swallow-tail conformation [25,26]. The polyamidoamine (PAMAM) is a class of commercial dendrimers.…”

Octakis(3‐azidopropyl)octasilsesquioxane: A Versatile Nanobuilding Block for the Efficient Preparation of Highly Functionalized Cube‐Octameric Polyhedral Oligosilsesquioxane Frameworks Through Click Assembly

“…[64][65][66] On the other hand, multimeric fluorescent molecules have been used as chemosensors for H + or metal ions, biological probes, optical brighteners, light-harvesting devices, or as potential compounds for organic lightemitting diodes. [67,68]…”

“…Synthetic multivalent glycoconjugates are interesting constructs for the study of carbohydrate–protein recognition processes and have a number of other potential practical applications, including the prevention of early adhesion of pathogens to host epithelial cells, the neutralization of viruses and toxins, the preparation of vaccines, and carbohydrate‐guided targeted drug delivery 64–66. On the other hand, multimeric fluorescent molecules have been used as chemosensors for H + or metal ions, biological probes, optical brighteners, light‐harvesting devices, or as potential compounds for organic light‐emitting diodes 67. 68…”
