“…It has also been reported that a reaction between luminol and 1 O 2 could produce inhibitors to the PSCL of luminol-Methylene Blue (or Eosin Y) system. [35] On the other hand, it has also been reported that reactions between luminol and 1 O 2 produce CL with a low CL efficiency as follows [37] : (7) (8) The rate constants of the above reactions were reported to be k 7 = (2.8 × 10 5 to 1.1 × 10…”

“…On the other hand, it was found that the type II mechanism could be neglected because there was no CL yielded even at a high concentration of O 2 that could be used to produce a sufficient amount of 1 O 2 . [34][35][36] Then, the PSCL was thought to be caused by a type I mechanism, where an electron was transferred from a luminol molecule to the 3 S*. As a result, a luminol radical and a dye-anion were produced.…”

“…Moreover, the CL efficiency of the type I mechanism was much larger than that of type II. [37] In the literature on PSCL, autosensitized CL [35] or photochemiluminescence (PCL) [38,39] of luminol, where no other dye-sensitizer existed but luminol itself acted as a kind of dye-sensitizer, was also mentioned. The transient absorption spectrum of luminol solution after illumination of a pulse laser of 347 nm showed light absorption at about 720 and 400-500 nm, which was considered to be the absorption of hydrated electron (e aq − ) and luminol radical, respectively.…”

“…In the air-saturated solution, the concentration of the dissolved oxygen was about 2.7 × 10 −4 mol/L. [35] This was about three times the luminol concentration (1 × 10 −4 mol/L). Therefore, the dissolved oxygen might have been in excess for the CL process involved.…”

Chemiluminescence (CL) on the time scale of microseconds to milliseconds from luminol solution after illumination of a 355 nm pulse laser is reported. It was found that the CL is the emission from 3-aminophthalate ion (AP*). In CL decay after the pulse laser illumination, a peak was observed from about 200 to 30 micros depending on the laser power and the luminol concentration. It seemed that there was a fast and slow decay process; their kinetics were greatly dependent on the laser power and the luminol concentration. Dissolved oxygen was involved in the CL and played the same role on the whole time scale of microseconds to milliseconds. Involvement of reactive oxygen species such as H(2)O(2), (1)O(2), O(2) (*-) and OH in the CL was examined by adding their scavengers. Experimental results suggested that the possibility of involvement of H(2)O(2) and (1)O(2) in the CL was low. The CL in time periods less than 50 micros might be related to *OH. The (*)O(2) (*-)-induced CL increased with time after 50 micros and became dominant on the time scale of milliseconds. The CL was considered to be caused by both the photoionization and type I reaction mechanisms.

A porous metal–organic framework [Ba(H 2 L LOMe 2− )·DMF·H 2 O]·2DMF ( UPC‐2 ) (H 4 L LOMe = 4ʹ,4ʹʹʹ‐(2,3,6,7‐tetramethoxyanthracene‐9,10‐diyl)bis([1,1ʹ‐biphenyl]‐3,5‐dicarbo‐xylic acid N,N‐Dimethylformamide [DMF]), which can act as an excellent chemiluminescence microreactor, is designed and constructed. In the framework of UPC‐2 , the catalytic Ba cluster and electron‐rich anthracene fluorescent centers are fixed and interconnected in an orderly fashion, and this can shorten the energy transfer path and weaken the relaxation of the chemiluminescence process. Meanwhile, the rhombic channels of UPC‐2 can provide a proper diffusion ratio of reactants to support a stable and continuous energy supply. The UPC‐2 chemiluminescence microreactor exhibits an ultrastrong and long‐lasting light emission, which possesses potential application in emergency lights and biological mapping. The concept of the chemiluminescence microreactor and its construction using a metal–organic framework as a platform will promote further research in the design and fabrication of functional MOFs for chemiluminescence applications.

A series of 4-styrylphthalhydrazides were synthesized and their chemiluminescence reactions were investigated. The chemiluminescence quantum yields as well as the emitters were variable depending on the electronic nature of the terminal substituents attached on the styryl groups. It was revealed that the excited phthalate ions were the emitters when they were highly fluorescent, while the energy transfer chemiluminescence from the excited phthalate ions to the phthalhydrazide anions took place when the fluorescence of the corresponding phthalate ions were very weakly fluorescent.
