Donor Acceptor

A series of all-trans acceptor–π-donor (acceptor) compounds (BAQ, SFQ, BLQ, and XJQ) were conveniently synthesised and characterised by infrared, nuclear magnetic resonance, mass spectrometry, and elemental analysis. Their photophysical properties, including linear absorption, one-photon excited fluorescence, two-photon absorption, and two-photon excited fluorescence, were systematically investigated. All the compounds show obvious solvatochromic effects, such as significant bathochromic shifts of the emission spectra and larger Stokes shifts in more polar solvents. Under excitation from a femtosecond Ti : sapphire laser with a pulse width of 140 fs, they all exhibit strong two-photon excited fluorescence, and the two-photon absorption cross-sections in THF are 851 (BAQ), 216 (SFQ), 561 (BLQ), and 447 (XJQ) GM respectively. A combination of density functional theory (DFT) and time-dependent density functional theory (TDDFT) approaches was used to investigate the relationships between the structures and the photophysical properties of these compounds. The results show that they may have a potential application as polarity-sensitive two-photon fluorescent probes.

A series of amphiphilic porphyrins appended with pyridinium cation and/or polyethylene glycol have been synthesized and fully characterized by 1 H NMR, IR and MALDI-TOF-MS. Their photophysical properties were determined and the singlet oxygen (1 O 2) quantum yields of these compounds are in the range of 0.30–0.61 in CHCl 3 and 0.048–0.18 in Tris buffer. The measured two-photon absorption (TPA) cross-sections σ(2) of these porphyrin derivatives are between 110 and 240 GM. These amphiphilic porphyrins show some photocleavage activities (10%–21%) towards the anionic DNA observed at 100 μM.
