Light and Dark Cycles Control the Structural Evolution of Photoresponsive Supramolecular Systems

Angewandte Chemie, EarlyView.
Here, we report a photoswitchable synthetic peptide that, under light energy cycles, exhibits supramolecular polymorphism coupled to darkness‐driven structural self‐selection. We demonstrate that light sustains a transient assembled state in the form of helical nanoribbons, hindering the system from undergoing a transition to the disassembled state ...

Organic multilayers as distributed Bragg reflectors

Applied Physics Letters, 1999
We report on a distributed Bragg reflector (DBR) operating in the IR spectral region, based on a fluorocarbon polymer (CFx) multilayer. In this organic structure, the periodic variation of the refractive index is obtained by embedding gold clusters in the CFx, resulting in a periodic CFx/CFx(Au) layered structure with a refractive index discontinuity ...
