Polymeric nanomaterials encapsulating fluorescent polyindole-nido- carborane: design, synthesis and biological evaluation [PDF]

Frontiers in Chemistry
The water-soluble nido-carborane was prepared by alkali treatment of o-carborane. A polymer PInd containing a polyindole structure was synthesized and employed to label the modified o-carborane. Subsequently, four polymeric nanomaterials were synthesized

Charge-Compensated Derivatives of Nido-Carborane [PDF]

Inorganics, 2023
This review summarizes data on the main types of charge-compensated nido-carborane derivatives. Compared with organic analogs, onium derivatives of nido-carborane have increased stability due to the stabilizing electron-donor action of the boron cage ...

Synthesis of Zwitter-Ionic Conjugate of Nido-Carborane with Cholesterol [PDF]

Molecules, 2021
9-HC≡CCH2Me2N-nido-7,8-C2B9H11, a previously described carboranyl terminal alkyne, was used for the copper(I)-catalyzed azide-alkyne cycloaddition with azido-3β-cholesterol to form a novel zwitter-ionic conjugate of nido-carborane with cholesterol ...

Preparation and cell imaging of a nido-carborane fluorescent complex based on multi-component polymerization. [PDF]

PLoS ONE
The biocompatibility of carborane was a difficult problem that had drawn a lot of study interest. Using multi-ion inlay binding, water-soluble polymers were created by encapsulating nido-carborane in diazaspirodecaniums such as para-poly-nido ...

Synthesis of a novel planar-chiral nido-carborane amino acid [PDF]

Russian Chemical Bulletin, 2021
The deboronation of enantiomers of planar-chiral benzyl (3-formamido-1,2-dicarba-closo-dodecaboran-1-yl)acetate gave the individual (RP)- and (SP)-enantiomers (ee > 98%) of a new amino acid containing a nido-carborane fragment, (3-ammonio-7,8-dicarba-nido-undecaboran-7-yl)acetic acid.

Nido-carborane encapsulated by BODIPY zwitterionic polymers: Synthesis, photophysical properties and cell imaging

Journal of Saudi Chemical Society, 2021
Carborane encapsulation was visualized by using fluoroboropyrrole (BODIPY) zwitterionic polymer as fluorescence marker. Firstly, a water-soluble fluorescent probe carrier was prepared by combining the BODIPY derivatives with poly (carboxybetaine ...

Nucleophilic Addition Reactions to 10-Acetonitrilium Derivative of nido-Carborane and Intramolecular NH⋯HB Interactions in N-Alkyl Amidines 10-RNHC(Me)=NH-7,8-C₂B₉H₁₁ [PDF]

Molecules
The addition reactions of water, alcohols, and primary and secondary amines to the 10-acetonitrilium derivative of nido-carborane were studied. Hydrolysis of 10-MeC≡N-7,8-C2B9H11 results in iminol 10-MeC(OH)=HN-7,8-C2B9H11, which, on treatment with a ...
