Dithienogermole (DTG)-containing oligo- and polysilsesquioxanes were prepared by hydrolysis/condensation of DTGs bearing one () or two trialkoxysilyl group(s) (). The reaction of gave a cage-type octasilsesquioxane with eight DTG groups at the edges () as a viscous oil, whereas the reaction of yielded a network polymer () as a self-standing film. showed a photoluminescence (PL) quantum yield (Φ...

Compounds belonging to a carbazole series have been identified as potent fungal plasma membrane proton adenosine triphophatase (H+-ATPase) inhibitors with a broad spectrum of antifungal activity. The carbazole compounds inhibit the adenosine triphosphate (ATP) hydrolysis activity of the essential fungal H+-ATPase, thereby functionally inhibiting the extrusion of protons and extracellular acidif...

Alzheimer's disease (AD) is a progressive and age-related neurodegenerative disorder affecting brain cells and is the most common form of "dementia", because of the cognitive detriment which takes place. Neuronal disruption represents its major feature, due to the cytosolic accumulation of amyloid β-peptide (Aβ) which leads to senile plaques formation and intracellular neurofibrillary tangles. ...

In the title mol-ecule, C12H8N2O2, the nitro group is tilted slightly with respect to the carbazole moiety [angle between the least-squares planes = 4.43 (9)°]. In the crystal, the mol-ecules are connected via pairs of N-H⋯O hydrogen bonds into dimers with -1 symmetry. The dimers in turn are arranged into layers parallel to (10-1).

There are two independent mol-ecules in the asymmetric unit of the title compound, C14H9Cl2N, in which the dihedral angles between the dichloro-vinyl unit (r.m.s. deviations = 0.0003 and 0.0009 Å), and the carbazole ring are 87.77 (3) and 72.90 (3)°.

Dithienylbenzothiadiazole (DTBT) is used as a building block in several molecules having application in organic light emitting devices (OLED) and organic photovoltaic (OPV) devices. Delayed fluorescence (DF) is the preferred design principle employed currently in OLED research. DTBT has excellent delayed fluorescence properties which makes this moiety a potentially viable OLED material. Here, t...

• Two different D -π-A molecules were synthesised by varying acceptor groups. Carbazole-benzylidenemalononitrile shows one of the highest solvatochromism (153 nm). Carbazole-benzaldehyde also high (86 The dicyanovinyl group is a more effective than formyl group. A pyridine linker leads to larger Stokes shift benzene ring. 4-(9′-Hexylcarbazol-3′-yl)benzaldehyde (Cz-Ph-CHO: 4 ) and 4-(9′-hexylcar...

The synthesis, as well as spectroscopic and thermochemical studies of a novel class of carbazole-4-phenylpyridine co-polymers are described. The synthesis was carried out by a simple and cheaper method compared to the lengthy methods usually adopted for the preparation of carbazole-pyridine copolymers which involve costly catalysts. Thus, two series of polymers were synthesized by a modified Ch...

In a previous report a specific color reaction of hexuronic acids with carbazole and sulfuric acid was described (1). In this reaction glucuronic and galacturonic acids, in free as well as in combined form in polyuronides, reacted with almost equal intensity. By decreasing the concentration of the acid and the temperature and time of heating, a modification of the carbazole reaction was obtaine...

A novel method for preparing α-norbornene methylene polystyrene macromonomer (NBMPSt) is reported. NBMPSt macromonomer ( Mn = 1.60 × 10 and PDI = 1.26) had glass transition temperature (Tg) of 107 C for polystyrene segment. Since the homopolymerization of NBMPSt macromonomer with number average molecular weight ( Mn ) 1.60 ×10 could not be carried out by ring-opening metathesis polymerization (...
