The synthesis, characterization, and photovoltaic properties of a series of four conjugatedpolymers containing 2‐aryl‐2H‐benzotriazoles and “bis(thiopheno)dialkylfluorenes” is described. The polymers were obtained via Suzuki‐polycondensation and comprise alternating electron rich and electron poor building blocks. The impact of systematic structural changes on the electronic and morphological properties

structured organic dyes (LM1 and LM2) based on methoxy substituted triphenylamine (MeO-TPA) as the electron donor, N-aryl benzotriazole as the electron acceptor have been designed and synthesized for watercontent detection in organicsolvents. Both dyes exhibit large stoke shift with solvatochromic properties and display apparent fluorescence quenching upon the addition of different amount of water in organic
