Fused silica microcapillaries were functionalized with spiropyran-polymer brushes using surface-initiated ring-opening metathesis polymerization. Based on the inherited spiropyran properties, the functionalized capillaries were successfully used to photoidentify solvents of different polarity when passing through the microcapillary in continuous flow. In the present study, six different solvent...

Application of terahertz (THz) electromagnetic waves offers several opportunities for quality inspection in various industries. The THz waves penetrate many kinds of materials such as pharmaceutical coating, paper, plastic, ceramic, cardboard, wood, clothing, etc. We investigated possibilities of applying a THz imaging system in transmission geometry using the organic DSTMS crystals as a THz ge...

Two dipolar merocyanines consisting of the same ?-conjugated chromophore but different alkyl substituents adopt very packing arrangements in their respective solid state with either H- or J-type exciton coupling, leading to ultranarrow absorption bands at 477 and 750 nm, respectively, due exchange narrowing. The social self-sorting behavior these push-pull chromophores mixed thin films is evalu...

Surface antigens, mRNA expression patterns and intravascular accumulation suggested that monocytes might directly participate in acute renal allograft rejection in rats. A flow cytometry-based cytotoxicity assay was used in the present study to analyze the cytotoxic activity of monocytes from the renal and the whole extrapulmonary vasculature of kidney graft recipients (DA to LEW or LEW to LEW)...

The bistability of molecular switches is an essential characteristic in their use as functional components molecular-based devices and machines. For photoswitches, light-driven switching between two stable states proceeds via short-lived changes the bond order electronically excited states. Here, bistable a ditertbutyl-substituted spiropyran photoswitch instead demonstrated by oxidation subsequ...

In this study, the optical properties and excited-state dynamics of unique self-assembled donor-acceptor (DA) merocyanine dye stacks from dimer up to octamer, prepared via dipole-dipole interactions, are reported in terms coherent exciton formation an excimer-like state. Our findings based on steady-state absorption/emission, time-resolved fluorescence, transient absorption (anisotropy) measure...
