Donor–π–acceptor (D–π–A) porphyrin based photo-sensitizers are extensively utilized in dye sensitized solar cells (DSSCs).

Novel D–A-?-A organic sensitizers for DSSCs based on benzothiadiazole internal acceptor (A) and N -substituted indolines fused with cyclopentane or cyclohexane as donor (D) the best PCE of 5.8% were reported.

A novel acceptor (A)–donor (D)–acceptor (A) molecular architecture for pseudocapacitor applications with imrpoved electrochemical performance is demonstrated.

A 67-year-old female developed excessive bleeding and thrombocytopenia following cardiovascular surgery. Her blood type was group A, D-. The only platelet products available in the transfusion service were random donor platelet concentrates from D+ donors. She was transfused with a pool of 6 D+ random donor platelet concentrates. Anti-D undetected in her pretransfusion serum by solid-phase anti...

A new series of luminescent 1,4-diazatriphenylene (ATP) derivatives with various peripheral donor units, including phenoxazine, 9,9-dimethylacridane and 3-(diphenylamino)carbazole, is synthesized and characterized as thermally activated delayed fluorescence (TADF) emitters. The influence of the donor substituents on the electronic and photophysical properties of the materials is investigated by...

Density Functional Theory (DFT) calculations were employed to investigate the structural characteristics, electronic properties, and nonlinear optical properties of Benzyne-Based Chromophores at B3LYP/6-31G(d,p) level. The effects on the hyperpolarizabilities of various donor and acceptor substituent (H, F, Cl, Br, Me, NH2, OH, NH3+, COOH, CHO, CN, NO,NO2 ) were studied. The results reveale...

A formula for the donor photoluminescence decay time in its dependence on the concentrations of donor D and acceptor A has been derived from equations for the non-radiative excitation energy transfer between randomly distributed donor and acceptor molecules within a nonactive medium. In the limit [D]/[A] -> 0 the formula becomes identical with that of Galanin [7], while in the absence of concen...
