Film-like conjugated microporous polymers (CMPs) are fabricated by the novel strategy of carbazole-based electropolymerization. The CMP film storing a mass of counterions acting as an anode interlayer provides a significant power-conversion efficiency of 7.56% in polymer solar cells and 20.7 cd A(-1) in polymer light-emitting diodes, demonstrating its universality and potential as an electrode interlayer in organic electronics.

This review focuses on alkyl length effects on solid-state fluorescence and mechanochromic behaviors, and the purpose is to arouse one's further attention to the alkyl-length effect in the design, synthesis and structure–property investigation of organic optoelectronic materials.

A poly(thieno[3,4‐b]‐thiophene/benzodi­thiophene) (PTB7)‐based polymer solar cell (PSC) with conventional structure can achieve a significant power conversion efficiency of 8.42%, which is realized by integrated optimization of both anode and cathode interlayers. The effects of a conjugated microporous polymer film as the anode interlayer are threefold: it enhances the contact with active layer, increases the work function and conductivity, and blocks electrons.

A new pure fluorescent blue HLCT-emitter was designed and synthesized. Highly efficient non-doped blue OLEDs with low efficiency roll-off were achieved.

2,6,9,10-tetra(p-dibutylaminostyryl)anthracene exhibited semi-disjointed frontier molecular orbital and multifunctional optical properties, including aggregation-enhanced emission, enhanced two-photon absorption activity, fluorescence response selectively to TM ions, and piezochromic luminescence. These are rarely found in cruciform configuration dyes.
