<p><P>PROBLEM TO BE SOLVED: To provide a polymer which has high singlet and triplet excitation levels, has excellent charge transport capability and electrochemical stability, enables lamination, is less susceptible to decomposition or the like by energization, and can provide a homogenous film quality, and an organic electroluminescent element material containing the polymer. <P>SOLUTION: The polymer has a repeating unit represented by general formula (1) and a crosslinkable group. In general formula (1), Ar<SP>11</SP>to Ar<SP>13</SP>each independently represents a divalent aromatic group which may have a substituent; Ar<SP>14</SP>and Ar<SP>15</SP>each independently represents an aromatic group which may have a substituent; Ar<SP>16</SP>and Ar<SP>17</SP>each independently represents a direct bond or a divalent aromatic group which may have a substituent; R<SP>11</SP>and R<SP>12</SP>each independently represents a hydrogen atom, an alkyl group which may have a substituent, an alkoxy group which may have a substituent, or an aromatic group which may have a substituent; and r represents an integer of 0 to 5. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
