Novel phenyl-substituted pyrazinoporphyrazine complexes of rare-earth elements: optimized synthetic protocols and physicochemical properties

Abstract

Novel synthetic protocols based on both template and direct methods were developed for phenyl-substituted pyrazinoporphyrazine complexes of rare-earth elements.

“…Синтез осуществлялся в соответствии с описанными протоколами для PhPorphErOAc [10], PhSubPcBBr [11] и PhNcLuPhPc [12]. Концентрации растворов, подготовленных для нанесения на подложку, составляли PhPorphErOAc (1.6 • 10 −4 М в смеси бензол : пиридин…”

Lanthanide–tetrapyrrole complexes: synthesis, redox chemistry, photophysical properties, and photonic applications

“…In 2018, Dubinina et al demonstrated that both templated and multi-step methods can be applied for efficiently synthesizing new lanthanide pyrazinoporphyrazine complexes with the assistance of both thermal and microwave irradiation techniques; the products were purified by simple precipitation from a MeOH : H 2 O (20 : 1 v/v) mixture, followed by washing with H 2 O, MeOH and acetone. 81 In 2019, by taking advantage of the larger size of Gd III compared to Fe II , Gottfried's group serendipitously obtained the template-controlled on-surface cyclopentamerization, rather than the expected formation of bis(phthalocyaninato) double deckers. 78 The resulting gadolinium(III) supernaphthalocyanine Gd-SNPc could be observed via scanning tunnelling microscopy (STM) (Fig.…”

In Memoriam – Brilliant Chemist, Professor Larisa Tomilova

“…[4,[16][17][18][19][20][21][22] Just recently the group of Professor Tomilova has published the chapter in the very interesting review in the «Macroheterocycles» entitled «Macroheterocyclic Compounds -a Key Building Block in New Functional Materials and Molecular Devices». [23] Last decades, the complexes of phthalocyanine analoguessubphthalocyanines, [19,24] naphthalocyanines, [20,25] tetrabenzoporphyrins [21,26] and porphyrazines, [27,28] diazepinoporphyrazines [29,30] were also widely studied. The approaches toward binuclear phthalocyanines of clamshell and ball types have been also developed.…”
