CCVJ is not a simple rotor probe.

Christopher Rumble et al.

The journal of physical chemistry. A, 116(44), 10786-10792 (2012-10-27)

The photochemistry of the rotor probe 9-(2-carboxy-2-cyanovinyl)julolidine (CCVJ) was studied to elucidate a curious effect of fluid flow previously reported. The apparent sensitivity to fluid motion observed in CCVJ but not in the closely related molecule 9-(dicyanovinyl)julolidine (DCVJ) is found

Differential scanning fluorescence approach using a fluorescent molecular rotor to detect thermostability of proteins in surfactant-containing formulations.

Elisabeth Ablinger et al.

International journal of pharmaceutics, 441(1-2), 255-260 (2012-12-04)

A differential scanning fluorimetry (DSF) based high-throughput screening assay with the fluorescent molecular rotor CCVJ (9-(2-carboxy-2-cyanovinyl)julolidine) was developed. CCVJ is mainly sensitive to viscosity and less to polarity in comparison to polarity-sensitive dyes like SYPRO Orange, which was commonly used

Fluorescence anisotropy of molecular rotors.

James A Levitt et al.

Chemphyschem : a European journal of chemical physics and physical chemistry, 12(3), 662-672 (2011-02-18)

We present polarization-resolved fluorescence measurements of fluorescent molecular rotors 9-(2-carboxy-2-cyanovinyl)julolidine (CCVJ), 9-(2,2-dicyanovinyl)julolidine (DCVJ), and a meso-substituted boron dipyrromethene (BODIPY-C(12)). The photophysical properties of these molecules are highly dependent on the viscosity of the surrounding solvent. The relationship between their quantum

Molecular rotor as a structural probe of glucan polymers: Amylopectin, phytoglycogen, and their β-limit dextrins as models.

Xingyun Peng et al.

Carbohydrate polymers, 250, 116859-116859 (2020-10-15)

Fluorescence emissions of molecular rotors (MRs) are affected by local restrictions to molecular motion, and therefore it was considered that MRs can be used as structural probes of biopolymers. In this study, 9-(2-carboxy-2-cyanovinyl)-julolidine (CCVJ), a hydrophilic MR, was used to

Structural characteristics requisite for the ligand-based selective detection of i-motif DNA.

Sagar Satpathi et al.

Organic & biomolecular chemistry, 17(21), 5392-5399 (2019-05-21)

Here, we have explored the light-up property of coumarin 343 (C343) selectively towards various i-motif DNAs based on the recognition of hemi-protonated cytosine-cytosine base pairing, unlike other DNA structures. We have also demonstrated the versatile ability of this i-motif ligand
