Fluorescence Enhancement of Covalently Linked 1-Cyano-1,2-diphenylethene Chromophores with Naphthalene-1,8-diyl Linker Units: Analysis Based on Kinetic Constants
of kinetic analysis of decay rate constants and theoretical calculations. Derivatives of 1‐cyano‐1,2‐diphenylethene dimer have a distorted cyclic structure when both ends are clipped with two naphthalene‐1,8‐diyl linker units. In contrast to the reference monomer derivative, which exhibits only slight fluorescence in solution (Φf<0.01, τf<0.1 ns), the dimer derivative shows high fluorescence quantum

A series of 1-arylnaphthalenes and 1,8-diarylnaphthalenes were synthesized by the Suzuki–Miyauracross-coupling methodology showing significant differentiation in the yields and selectivity between aryl rings with electron donating (higher yields), and electron withdrawing substituents (lower yields). These results strongly support the relation between the nucleophilicity of the boronate complex and

4-diethynylbenzene linker molecule. Cage compounds 1-4 and framework 14 exhibited exceptional high ideal selectivity (36/1-138/1) in adsorption of CO(2) over N(2) under the standard temperature and pressure (STP, 20 °C, 1 bar). Gas adsorption studies indicate that the high selectivity is provided not only by the amino group density (mol/g), but also by the intrinsic pore size of the cage structure (distance between

Light‐harvesting systems are an important way for capturing, transferring and utilizing lightenergy. It remains a key challenge to develop highlyefficient artificial light‐harvesting systems. Herein, we report a supramolecular co‐assembly based on lower‐rim dodecyl‐modified sulfonatocalix[4]arene (SC4AD) and naphthyl‐1,8‐diphenyl pyridinium derivative (NPS) as a light‐harvesting platform. NPS as
