342638-54-4 Usage
Description
MCBP, 3,3-Di(9H-carbazol-9-yl)biphenyl, also known as mCBP, is an isomer of CBP, 4,4′-Di(9H-carbazol-9-yl)-1,1′-biphenyl. The unique meta-linkage in mCBP restricts conjugation to the central biphenyl, which prevents excimer formation and leads to a higher triplet energy of 2.8 eV.
Uses
Used in Organic Light Emitting Diodes (OLEDs) Industry:
MCBP, 3,3-Di(9H-carbazol-9-yl)biphenyl, is used as a host material for phosphorescent OLEDs due to its high triplet energy of 2.8 eV. This property allows for efficient energy transfer to phosphorescent dopants, resulting in improved device performance and color quality.
Used in Host Materials for Organic Light Emitting Diodes (OLEDs):
MCBP, 3,3-Di(9H-carbazol-9-yl)biphenyl, is utilized as a host material in the fabrication of OLEDs, particularly for blue-emitting devices. Its high triplet energy and meta-linkage contribute to enhanced device efficiency and color stability, making it a valuable component in the design and development of advanced OLED technologies.
Check Digit Verification of cas no
The CAS Registry Mumber 342638-54-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,2,6,3 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 342638-54:
(8*3)+(7*4)+(6*2)+(5*6)+(4*3)+(3*8)+(2*5)+(1*4)=144
144 % 10 = 4
So 342638-54-4 is a valid CAS Registry Number.

Model compounds of some polychlorobiphenyl congeners, viz., 4,4′-dihalobiphenyls, were synthesized. These compounds can be successfully utilized by a chemical method for the in situ generation of arynes followed by the reaction with carbazole in order to prepare appropriate bis(carbazolyl)biphenyls as components for molecular electronics and OLED devices.
