Convenient Route

A convenient route was successfully developed for the synthesis of novel heterocycles such as pyrazolo[3,4-b]pyrrolo[2,3-d]pyridines (PPP) from pyrazolo[3,4-b]pyridines in good yield. The PPP derivatives synthesized were further studied for their photophysical properties, and it was observed that absorption and emission λmax changed, owing to the substituent effect at 4 positions. These compounds were obtained from highly reactive starting materials, 5-aminopyrazoles and α-acetyl γ-butyrolactone.Key words: α-acetyl γ-butyrolactone, pyrazolo[3,4-b]pyrrolo[2,3-d] pyridine, absorption, emission, fluorescence.

The photophysical properties of heteroleptic iridium(iii) cyclometalates [4-(2-RCB)ppy]2Ir(acac) (R = H, alkyl, aryl) with 2-R-o-carboranes at the 4-position of the ppy ligands are significantly affected by the 2-R substituent on o-carboranes.
