Pyridine-Conjugated Pillar[5]arene: From Molecular Crystals of Blue Luminescence to Red-Emissive Coordination Nanocrystals
Xin‐Yue Lou, Ying‐Wei Yang
Abstract
A luminescent molecular crystal (P5bipy) and a Cu(I)-coordinated luminescent nanocrystal (Cu(I)-P5bipy) have been prepared concurrently using one conjugated pillar[5]arene macrocycle via a facile supramolecular self-assembling strategy. The molecular crystal shows enhanced luminescence compared with unmodified pillar[5]arene, attributed to its conjugated structure and staggered packing mode, while the coordination nanocrystal exhibits well-defined crystalline structures and long-lifetime triplet state emission along with pronounced solvochromic features.
