Article Synopsis
- - The text discusses two processes, singlet fission (SF) and triplet-triplet annihilation upconversion (TTA-UC), which involve interactions between high-energy singlet and low-energy triplet excitons in dendritic macromolecules.
- - It introduces dendrimers of varying generations (1-4) made from trimethylolpropane cores and bis-MPA dendrons, which help investigate how these dendrimer structures affect the generation and decay of multiexcitons, particularly through changes in interchromophore interactions.
- - Results show that as dendrimer generation increases, specific ordered sites become influential in multiexciton dynamics, with higher generations enhancing TTA-UC and leading
Quantum interference (QI)-the constructive or destructive interference of conduction pathways through molecular orbitals-plays a fundamental role in enhancing or suppressing charge and spin transport in organic molecular electronics. Graphical models were developed to predict constructive versus destructive interference in polyaromatic hydrocarbons and have successfully estimated the large conductivity differences observed in single-molecule transport measurements. A major challenge lies in extending these models to excitonic (photoexcited) processes, which typically involve distinct orbitals with different symmetries.
