DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link, add「http://dx.doi.org/」「 http://dx.doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: http://dx.doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing references, you should also cite the DOI if the article has one. If your citation guideline does not include DOIs, you may cite the DOI link.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

The synthesis and characterization of hyperbranched poly(p-methylenetriphenylamine) (PMTPA) are described. We discovered that N-[4-(tosyloxybutyloxymethyl)phenyl]-N,N-diphenylamine showed unexpected chemical reactivity and polymerized to form hyperbranched PMTPA under neat conditions. The hyperbranched PMTPA was electrochemically active and was deposited on electrode surface when oxidized. The SEM study revealed that electropolymerization of PMTPA would form uniform coating onto ITO surface. Polymeric light-emitting diodes (PLEDs) employing electroactive polymers of either hyperbranched PMTPA or linear Poly(4-vinyltriphenylamine) (PVTPA) as hole-transport layer in the EL device of ITO/electrochemically polymerized HTL/EML(PVK-PBD-Ir(ppy)3)/Mg/Ag demonstrated the brightness over 20,000 cd/m2 and low turn-on voltage. In particular, the device performance was very steady regardless of the thickness of the PMTPA layer, ranging from 4 to 10 nm. 
In addition, PLEDs using a series of linear poly(4-vinyltriphenylamines) (PVTPAs) as hole-transport layer were fabricated. The relationships between their molecular weight, thermal stabilities, surface morphology and electronic properties were investigated. The SEM study revealed that electropolymerization of lowest molecular weight (~2700 g/mol) of PVTPA with 3 CV cycles would form uniform coating on ITO surface and show the highest brightness (~34,400 cd/m2) among others. However, surface modification tactic has to be adopted for the other higher molecular weight of PVTPAs because numerous cracks were observed on the electrode surface. We discovered applying some homogeneous thin film primed the ITO anode prior to the electrodeposition of PVTPA would reduce dramatically the uneven distribution of the electroactive layer and eventually have a smooth, crack-free film surface.
By the way, our experiments also showed that the PU polymer could also be applied for flexible PLED with similar performance enhancement. Based on the promising results, we concluded that OPV-IPDI was a good hole-transport material for light-emitting diode application.
