A series of novel carbazole-based mono- and dinuclear gold(I) complexes with various lengths of alkyl chains were synthesized and characterized using nuclear magnetic resonance spectroscopy, elemental analysis and single crystal X-ray diffractometry. Their aggregation-induced emission characteristics were investigated by ultraviolet/visible and photoluminescence spectroscopy. Their solid-state mechanochromic luminescence behavior was also studied by photoluminescence spectroscopy. All gold(I) complexes based on a carbazole scaffold structure exhibited excellent aggregation-induced emission properties. Luminogens 1 and 2 showed reversible mechanochromism phenomena involving luminescent color transformation from yellow-green to green. Luminogens 3 and 4 exhibited switchable mechanochromic luminescence behavior involving fluorescent color change from colorless to green. The solid-state fluorescence of luminogens 5 and 6 can be switched between weak and strong fluorescence by mechanical force stimulus, and this conversion is irreversible.

Three soluble imine polymers based on a combination of two units: 3, 6-(N-hexyl) carbazolyldiyl and 1, 4-phenylene in the main polymer chain have been synthesized by solution polycondensation method from 1, 4-diaminobenzene or 3, 6-diamino-N-hexylcarbazole and 3, 6-diformyl-N-hexylcarbazole or terephthaldehyde and their structure was analysed by spectroscopic methods. Presence of linear and cyclic oligomers was observed by gel permeation chromatography and assigned after liquid chromatography separation and mass spectroscopy analysis.
