Abstract

The novel thiophene-chalcone compound (2), phthalonitrile derivatives bearing thiophene-chalcone group (3 and 4) and their zinc (II) (ZnPcs) (3a and 4a) and magnesium (II) (MgPcs) (3b and 4b) phthalocyanine compounds were synthesized in this study. The structure of all these new compounds were elucidated by spectroscopic techniques like IR, ¹ H NMR, ¹³ C NMR (for compounds 2, 3 and 4), MALDI–TOF mass and UV-Vis. The fluorescence quantum yields and lifetimes (photophysical properties), and the singlet oxygen and photodegradation quantum yields (photochemical properties) of thiophene bearing chalcone substituted ZnPcs (3a and 4a) and MgPcs (3b and 4b) were studied in DMSO (dimethylsulfoxide) to determine if they are convenient photosensitizers for photodynamic therapy (PDT) applications.

查尔酮取代含噻吩单元的锌(II)和镁(II)金属酞菁的光物理、光化学性质

本文合成了新型噻吩-查尔酮化合物(2)、含噻吩-查尔酮基团的邻苯二腈衍生物(3和4)及其锌(II) (ZnPcs) (3a和4a)和镁(II) (MgPcs) (3b和4b)酞菁化合物。通过IR、1h NMR、13c NMR(针对化合物2、3和4)、MALDI-TOF质量和UV-Vis等光谱技术对这些新化合物的结构进行了鉴定。在二甲基亚砜(DMSO)中研究了含噻吩的查尔酮取代的ZnPcs (3a和4a)和MgPcs (3b和4b)的荧光量子产率和寿命(光物理性质)，以及单线态氧和光降解量子产率(光化学性质)，以确定它们是否是光动力治疗(PDT)应用的方便光敏剂。

期刊介绍： The Journal of Inclusion Phenomena and Macrocyclic Chemistry is the premier interdisciplinary publication reporting on original research into all aspects of host-guest systems. Examples of specific areas of interest are: the preparation and characterization of new hosts and new host-guest systems, especially those involving macrocyclic ligands; crystallographic, spectroscopic, thermodynamic and theoretical studies; applications in chromatography and inclusion polymerization; enzyme modelling; molecular recognition and catalysis by inclusion compounds; intercalates in biological and non-biological systems, cyclodextrin complexes and their applications in the agriculture, flavoring, food and pharmaceutical industries; synthesis, characterization and applications of zeolites. The journal publishes primarily reports of original research and preliminary communications, provided the latter represent a significant advance in the understanding of inclusion science. Critical reviews dealing with recent advances in the field are a periodic feature of the journal.
