A fully conjugated meso-boron-substituted porphyrinoid combining Lewis acidity with redox-switchable aromaticity

Nature Communications
The structural motif of porphyrin is relevant for many essential biological processes and has emerged as a versatile component of functional materials. Here, we introduce a thiophene-based porphyrinogen having electron-deficient boron atoms in all four ...

Ultra-photostable small-molecule dyes facilitate near-infrared biophotonics

Nature Communications
Long-wavelength, near-infrared small-molecule dyes are attractive in biophotonics. Conventionally, they rely on expanded aromatic structures for redshift, which comes at the cost of application performance such as photostability, cell permeability, and ...

The apparent and hidden variables for optimizing and functionalizing non-alternant nanographenes: A comprehensive study

Nano Trends
Atomically precise non-alternant isomers of short armchair graphene nanoribbons (AGNRs) with A = 2 armchair and Z = 3, 4 zigzag rings have been recently synthesized by introducing Stone-Wales (SW) moieties, pursuing open shell magnetic states for ...
