Tags: The modification of the methyl group of 4'-(p-tolyl)-2,2':6',2''-terpyridine produced the novel unnatural amino acid 3-(4-([2,2':6',2''-terpyridin]-4'-yl)phenyl)-2-aminopropanoic acid (phet). Mononuclear heteroleptic ruthenium complexes of the general formulae [Ru(L1)(L2)](PF6)2 (L1 = 2-acetylamino-2-(4-[2,2':6',2'']terpyridine-4'-yl-benzyl)-malonic acid diethyl ester, (phem), 3-(4-([2,2':6',2''-terpyridin]-4'-yl)phenyl)-2-aminopropanoic acid, (phet), and L2 = 2,2':6',2''-terpyridine (tpy), 4'-phenyl-2,2':6',2''-terpyridine (ptpy), 4'-(p-tolyl)-2,2':6',2''-terpyridine (mptpy)), as well as the homoleptic [Ru(phem)2](PF6)2 and [Ru(phet)2](PF6)2, were synthesized and characterized by means of NMR spectroscopic techniques, elemental analysis, and high-resolution mass spectrometry. The photophysical properties of the synthesized complexes were also studied., ruthenium; terpyridine; photophysical properties; unnatural amino acid
