The recent focus on SERS-active materials has shifted from conventional plasmonic surfaces to alternative 3D structures and semiconductors.

Carbonyl vs. dicyanovinylene functionalization in indenofluorenes leads to substantial differences in solid-state packings and results in significant variations (×1000) in electron mobilities.

A systematic series of fluorescence chemosensors based on cyclotriphosphazene derivatives were designed, synthesized, and evaluated for their sensing behaviors toward metal ions.
