51325-91-8 Usage
Description
4-(Dicyanomethylene)-2-methyl-6-(4-dimethylaminostyryl)-4H-pyran (DCM) is a red laser dye characterized by its dicyanomethylene electron acceptor and dimethylaniline electron donor groups. It features a π-conjugated 4H-pyran-4-ylidiene bridge that connects the acceptor and donor groups, making it suitable for use as a dopant and in organic solid-state lasers. DCM is known for its red/brown crystalline appearance.
Uses

DCM serves as a capping layer in OLEDs, enabling the conversion of blue to red-colored emission. This application takes advantage of DCM's red laser dye properties to achieve desired color outputs in display technologies.
3. Used in Energy Transfer Enhancement:
DCM may find potential applications in enhancing the energy transfer of various devices, such as metal-organic frameworks (MOFs), dye-sensitized solar cells (DSSCs), and polarity sensors. Its use in these applications is due to its ability to improve the efficiency of energy transfer processes in these technologies.
4. Used in Pharmaceutical Applications:
Although not explicitly mentioned in the provided materials, DCM's unique chemical structure and properties may also make it a candidate for pharmaceutical research, particularly in the development of new drugs or drug delivery systems. Further investigation would be required to explore this potential application.
Check Digit Verification of cas no
The CAS Registry Mumber 51325-91-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,3,2 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 51325-91:
(7*5)+(6*1)+(5*3)+(4*2)+(3*5)+(2*9)+(1*1)=98
98 % 10 = 8
So 51325-91-8 is a valid CAS Registry Number.

A luminescence molecular switch via modulation of PET and ICT processes in DCM system

, p. 607 - 613 (2017)
A novel versatile dicyanomethylene-4H-pyran (DCM) based derivative bearing ferrocenyl group (DCM-N-Fc) is designed as modulator to construct “off-on” logic operation. The optical properties of DCM-N-Fc are characterized by absorption and steady-state fluorescence technique, showing that the fluorescence from DCM chromophore via intramolecular charge transfer (ICT) is strongly quenched by photoinduced electron transfer (PET) process from ferrocene moiety. In contrast with the references (DCM-N and DCM-Fc), the fluorescence of DCM-N-Fc can be triggered by oxidizing ferrocenyl unit either chemically or electrochemically, exhibiting a characteristic emission modulation at around 610 nm with an electrofluorochromic behavior. Furthermore, the free energy and the fluorescence lifetime in the PET path verify the thermodynamic feasibility. Cyclic voltammetry, absorption spectroscopy, time-resolved fluorescence as well as DFT calculation have been used to elaborate the manipulation via both PET and ICT processes.
