The stable coordinated metallo-complexes based on 2,2′:6′,2″-terpyridine(tpy)and its derivatives have been widely researched for various wide-ranging applications in photoelectronics,catalysis,sensor,pho-toluminescence,and so on.However,the most reported studies ignored the comprehensive comparison between structures modified by different positions and photoluminescence.Herein,we design a series of metallo-complexes which were assembled with tpy substituted triphenylamine(TPA)at different po-sitions and metal ions and explored their photophysical properties.In the solution state,MLE2 based on the 5,5″-positions modification showed the highest PLQYs and PL intensity.With the increase of solvent polarity,MLB2 exhibit the largest redshift.In the solid state,from MLA2 to MLE2,the emission colours are gradually red-shifted from yellow to red.The findings in this work may pave a new way to design functional metallo-complexes,not just for PL properties.
