Excitation-Wavelength-Dependent Light-Induced Electron Transfer and Twisted Intramolecular Charge Transfer in <i>N</i>,<i>N</i>-Bis(4′-<i>tert</i>-butylbiphenyl-4-yl)aniline Functionalized Borondipyrromethenes
functionalized borondipyrromethene (BODIPY) dyads, Dyads 1–3, containing the BBA group tethered to BODIPY moiety either directly or through a phenyl or alkynyl phenyl spacers are synthesized, and the light-mediated chargetransfer within the chromophores has been systematically investigated. The crystal structure of Dyad-1 showed a tilt of 44.2° between the BODIPY and BBA molecular planes and intermolecular
A novel dyad 2 based on C(60) and bis(4'-tert-butylbiphenyl-4-yl)aniline (BBA) donor has been synthesized and characterized. Cyclic voltammetry (CV) and UV-vis spectra of 2, 61-phenyl-1, 2-methanofullerene[60] 4, 1,2-methanofullerene[60] 5, and BBA were measured and analyzed. CV measurements showed that a reversible oxidation wave of 2 was positively shifted by 40 mV compared to that of BBA. More remarkably
Excitation-dependent electron exchange energy and electron transfer dynamics in a series of covalently tethered <i>N</i>,<i>N</i>-bis(4′-<i>tert</i>-butylbiphenyl-4-yl)aniline – [C<sub>60</sub>] fullerene dyads <i>via</i> varying π-conjugated spacers
86–99.6% (Dyad-3–Dyad-1) quantum efficiency and a CR process with kCR values [kCR ∼ (1010–108) s−1] up to three orders greater than kCS of the respective dyads. Both the processes, CS and CR, upon C60 excitation and the CR process upon BBA excitation show distance dependent rate constants with exponential factor β ≤ 0.5 Å−1, and electrontransfer is concluded to occur through a covalently linked conjugated
Photo-induced energy and electron transfer in carboxylic acid functionalized bis(4′-tert-butylbiphenyl-4-yl)aniline (BBA)-substituted A3B zinc porphyrins
zinc porphyrins containing BBA attached to the three meso-positions of the porphyrin macrocycle via varied spacers i.e., directly connected, phenyl, and ethoxy phenyl, and carboxylicacid functional group at the other meso-position, were synthesized and fully characterized using 1H, 13C NMR, MALDI-TOF, HRMS (ESI+), UV-visible and fluorescence techniques. The steady-state absorption spectrum of Tetrad-1
