Purpose Family businesses (FBs) play an important role in economies across the world. FBs are consistently associated with specific attributes and expectations, which is something that points towards notion can be regarded as a “brand” on their own. The purpose of this paper to examine whether have actually become eyes wider population. Design/methodology/approach empirical investigation based “Personal Construct Theory” (PCT), developed by George R. Kelly. According theory, human beings...
We report the synthesis of a fluorescent polycyclic aromatic hydrocarbon dye with "symmetry‐broken" core, derived from related hexa‐peri‐benzo¬coronene core fluoranthene subunit. The fluorophore is composed pure carbon skeleton without heteroatoms and exhibits remarkable photo¬luminescence properties photoluminescence quantum yield up to 67% in toluene, exceeding that parent hexa‐peri‐benzocoronene by factor 30. single crystal X‐ray structure reveals distorted structure, which responsible...
Fluorescent dyes are applied in various fields of research, including solar cells and light-emitting devices, as reporters for assays bioimaging studies. with an added high dipole moment pave the way to nonlinear optics polarity sensitivity. Redox activity makes it possible switch molecule's photophysical properties. Diaminodicyanoquinone derivatives possess moments, yet only low fluorescence quantum yields, have therefore been neglected fluorescent dyes. Here we investigate properties...
Molecular aggregation alters the optical properties of a system as fluorescence may be activated or quenched. This is usually described within well-established framework H- and J-aggregates. While H-aggregates show nonfluorescent blueshifted absorption bands with respect to isolated monomer, J-aggregates are fluorescent displaying redshifted peak. In this publication, we employ combined approach experiment theory study complex features photophysical diaminodicyanoquinone derivatives, which...
Abstract In nature, molecular environments in proteins can sterically protect and stabilize reactive species such as organic radicals through non-covalent interactions. Here, we report a near-infrared fluorescent rotaxane which the stabilization of chemically labile squaraine fluorophore by coordination tetralactam macrocycle be controlled electrochemically. The switched between two co-conformations wheel either stabilizes or exposes fluorophore. Coordination affects squaraine’s stability...
Abstract Fluoreszenzfarbstoffe werden in verschiedenen Forschungsbereichen eingesetzt, darunter Solarzellen, lichtemittierende Dioden, Reporter für Assays oder Bioimaging‐Studien. Ein zusätzliches hohes Dipolmoment ebnet den Weg zu nichtlinearer Optik und Polaritätsempfindlichkeit. Die Redoxaktivität ermöglicht es zudem, photophysikalische Eigenschaften der Moleküle verändern. Diaminodicyanochinon‐Derivate besitzen hohe Dipolmomente, aber nur geringe Fluoreszenzquantenausbeuten galten daher...
