A series of pyrrolopyrrole aza borondipyrromethene derivatives have been designed and synthesised as two-photon fluorescent probes. The bisalkynyl analogues, having a donor–π–donor quadrupolar skeleton, show a red-shifted Q band at ca. 700 nm in toluene and a two-photon absorption (TPA) cross-section up to 2349 GM at 1040 nm. To enable these dyes to be used for subcellular imaging, a branched oligoethylene
A facile and versatile synthesis of ynamines via C(sp)–N bondformation was established. We installed an electron-withdrawing phosphoryl group onto the ynamines to isolate them by column chromatogr...
