ʻO 4,4′-diaminobiphenyl-2,2′-dicarboxylic acid, i ʻike ʻia ʻo DABDA, he mea hoʻohui kemika me ka molecular formula C16H14N2O4.He pauka keʻokeʻo keʻokeʻo i hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka ethanol, acetone, a me ka methanol.Loaʻa iā DABDA nā waiwai kemika kūʻokoʻa e kūpono ai i nā noi he nui.
Loaʻa ka hoʻohana nui ʻana o kēia pūhui kemika ma ke kahua o ka noiʻi polymer a me ka hoʻomohala ʻana.Ma muli o kona kūpaʻa wela kiʻekiʻe a me nā waiwai mechanical maikaʻi, hoʻohana mau ʻia ʻo DABDA ma ke ʻano he hale kūkulu hale i ka synthesis o nā polymers kiʻekiʻe.Loaʻa i kēia mau polymers ka nui o nā noi, me nā uhi, nā mea hoʻopili, a me nā insulators uila.
Eia kekahi, hōʻike ʻo DABDA i nā waiwai electrochemical maikaʻi loa, e lilo ia i moho kūpono no ka hoʻomohala ʻana i nā mea hana electrochemical kiʻekiʻe.Hoʻohana nui ʻia ia i ka hana ʻana i nā electrodes no nā supercapacitors a me nā pā lithium-ion.Me kona conductivity kūikawā a me ka paʻa, hāʻawi ʻo DABDA i ka hana holoʻokoʻa a me ke ola o kēia mau ʻōnaehana mālama ikehu.
