A luminescence supramolecular hyperbranched polymer is reversibly fabricated by successively adding acid and base to a solution of an AB2 platinum(II) monomer in dichloromethane on the basis of acid-base controllable host-guest recognition of dibenzo[24]crown-8 moieties with dialkylammonium ion centers.

Pentalene has recently received a considerable amount of attention as a ligand in sandwich-type transition metal complexes. In contrast, dibenzo[a,e]pentalene (hereafter denoted as dibenzopentalene), which is more -extended than pentalene, has received less attention, despite its potential usefulness as a building block of ladder-type -conjugated molecules, which have recently received growin...

Crosslinkable hole transport materials (HTMs) with high triplet energies would have a balance of carrier injection into the emitting material layer, suppressing exciton quenching and resulting in high-performance solution-processed organic light-emitting diode (OLED) devices. Two novel crosslinkable HTMs different central units, N2, N8-di-p-tolyl-N2,N8-bis(4-vinylphenyl)dibenzo[b,d]thiophene-2,...
