For the past two years, AsianJOC has brought you excellent research for free. This trial period is now over. Please consider a subscription or recommend the journal to your librarian. AsianJOC is owned by ACES, a consortium of Asian chemical societies. The individual societies will benefit from the revenues and so will the communities they serve.
There will be an updated version of our iPad app in the App Store in a few days. It fully supports subscriptions and will also work on the iPhone.

- Light-Harvesting in the Near-Infrared Region: Dye-Sensitized Solar Cells Sensitized with Asymmetric Ring-Expanded Zinc(II) Phthalocyanines
Satoshi Yamamoto, Takuro Ikeuchi, Prof. Dr. Shogo Mori and Prof. Dr. Mutsumi Kimura
Article first published online: 28 JUL 2014 | DOI: 10.1002/ajoc.201402117
Seeing red: The ring-expanded zinc phthalocyanine sensitizer FcS1 can convert red and near-infra red light regions between 600–860 nm into electronic energy in dye-sensitized solar cells. The inclusion of fused rings resulted in tailored HOMO and LUMO energy levels and extension of the π-electron system.
- A Two-Photon Probe for Near-Membrane Zinc Ions
Dr. Kailash Rathore, Dr. Chang Su Lim, Young Lee, Dr. Hee Jung Park and Prof. Dr. Bong Rae Cho
Article first published online: 28 JUL 2014 | DOI: 10.1002/ajoc.201402112
It takes two to probe: A two-photon probe for near-membrane zinc ions is reported. This probe is derived from a fluorene derivative that has a long-chain hydrocarbon tail and a zinc ion receptor. It predominantly stains the plasma membrane and emits strong two-photon excited fluorescence upon binding with zinc ions.
- Function of CH2 Addends on 54π Fullerene Acceptors
Shan Chen, Zuo Xiao, Dan He, Lina Ma and Prof. Liming Ding

Me two! Stepwise replacement of o-quinodimethane addends to 54π fullerenes with CH2 addends improves electron mobility of fullerene, enhances crystallinity of poly(3-hexylthiophene), increases the number of donor-acceptor interfaces, and reduces bimolecular recombination, thus enhancing the power conversion efficiency of fullerene:P3HT solar cells remarkably from 2.26 % to 6.25 %.
- Domino Knoevenagel Condensation/Aza-Ene Addition/N-Cyclization Route to Functionalized Imidazo[1,2-a]pyridines and Pyrido[1,2-a]pyrimidines
Sathiyamoorthi Sivakumar and Raju Ranjith Kumar
Article first published online: 23 JUL 2014 | DOI: 10.1002/ajoc.201402100
One-pot wonder! The syntheses of imidazo[1,2-a]pyridines and pyrido[1,2-a]pyrimidines were carried out by using a one-pot three-component protocol. The reaction proceeds in a single step through a domino Knoevenagel condensation/aza-ene addition/imine–enamine tautomerization/chemoselective N-cyclization sequence of reactions (In=indolyl).
- Application of Regio- and Stereoselective Functional Group Transformations of Chiral Aziridine-2-carboxylates
Prof. Dr. Hyun-Joon Ha, Jae-Hoon Jung and Prof. Dr. Won Koo Lee
Article first published online: 23 JUL 2014 | DOI: 10.1002/ajoc.201402098
Boxing clever: This Focus Review highlights the chemistry of chiral aziridine-2-carboxylates as building blocks based on regio- and stereoselective functional group transformations of the carboxylate group and aziridine ring. This chemistry is exemplified by the efficient and highly stereoselective synthesis of many biologically important amines, including several natural products.
